Improvement in stop-motion for spooling-machines

.IMPROVEMENT IN STOP-MOTION' FOR SPOOLINCi- MACHVINES The Schedule referred t0 in these Letters Patent and making part of the same.

To all 'whomI it may concern Be it known that I, SAMUEL SEMPLE, Jr., of Mount Holly, in the county of Burlington, and in the State ot" New Jersey, have invented certain newand useful i Improvements in Cop-Spool Machines 5 and do hereby declare that the following is a full, clear, and exact descriptinn thereof', reference being had to the accompanyin g drawings and to the letters of reference marked thereon making a part of this specification.

'lhel nature of my invention consists inthe construction and arrangement of a cop-spooling machine, for doubling three or more strands of yarn or thread off cops of yarn or hobbins on to one bobbin.'

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure lis a side elevation, part in section, of my machine, and

Figure 2 is a planview ofthe same. y A represents the bed-piece of my macliine,at one end of which are two standards, B B, having between them at their upper ends a round felt or cloth-covered bar, C. v

On the rearor outer side of the har C, a-re placed aA number of wire guides, a, a.

Under this har the cops D D, from o which the yarn or thread is to be takemare placed.

At the other end of the bed A is a frame, E, through which passes anupright shaft, G, providedwith a pulley, H, to be connected with an engine or machinery| for the purpose of revolving the shaft.

Upon the"upper end of the shaft G is placed the bobbin or spool I, on which the doubled yarn or thread is tiobe wound.

At a suitable distance above its lower end on the shaft G, is securelyfastened a collar with two horizontal arms, J J, for a purpose that will be l'lereinafter described.

On the bed-plate A, between the frames B C and E, is a small metal frame, K, Vin which are pivoted a number of drop-wires, b b, which pass through a slotted upright guide-plate, L, and are then bent upward, and their upper ends forming hooks, c c.

Under the wires b bin the frame K, is pivoted a lever, nearly l'ialanced.

One end, M, of this lever is Ty-shaped, as shown in iig. 2, and extends under the wires b b nearly to the guide-plate L, while the other end, N, extends to near the shaft G, and has at its outer end a wing or plate, O, as shownin fig..1, this being so arranged that when the lever M N is balanced, or nearly so, the plate O will be below the arms J J on the shaft G, and not interfere with the revolution of said shaft.

The strands of yarn or thread are taken from the copsD D below and passed through the wire guides a a, over the bar C, and thence through the hooks c c of the drop-wires b b to the b obbin I.l

Before reaching the bobbin I, the strands pass over a guide-wire, d, extending from the frame E, so as to guide them onto the bobbin.

By this arrangement the drop-wires b b are raised to the height of the slots inthe guide-plate L, as shown in iig. l., and the plate-lever M N is nearlyl balanced.

When either strand of yarn breaks, the weight of the drop-wire is sufficient to lower the T-shaped arm M, raising the arm N, so that the arm J on the shaft 'or spindle G is caught by the plate O, causing it to stop, thereby arresting the motion of the bobbin I,

and preventing less than the propel' number of strands passing on to the bobbin.

It will be seen that the strands of yarn are kept separate until they are nearly on the bobbin, thus getting an exactly uniform tension on each thread, which is of the first importance in securing a good, evenly-twisted thread.

Having thus fully described my invention,

What I .claim as new, and desire to secure by Letters Patent, is

The arrangement within the standards B B and frame E, of bar G, with wires u, a, spindle G, with pulleyH and arms J J, frame K, drop-wires b b, guideplate L, lever M N, stop O, and guide d, all constructed and operating as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 12th day of January, 1870.
